- Disable VM snapshots during firmware updates
-
Post-Installation Verification
- Monitor virtual CPU ready time via Hyper-V Manager
- Re-authenticate site-to-site VPN tunnels
-
Legacy Environment Considerations
- Maintain offline backups of v5.6.4 virtual disks
- Schedule vulnerability scans to confirm CVE remediation
End of Lifecycle Advisory
While this update extends security coverage for v5.6.x deployments until Q3 2026, Fortinet recommends:
- Migrating to FortiOS 7.4.x for AI-driven threat intelligence features
- Evaluating FortiGate 3700F hardware for performance-intensive workloads
- Enabling extended logging for compliance audit trails
